Abstract: Described embodiments provide a device configured to be coupled to a shared bus. The device includes a magnetic field sensing element to sense a magnetic field. Upon receiving a configuration command over the shared bus, the device determines whether a parameter of the sensed magnetic field meets a predetermined criteria. If the parameter of the sensed magnetic field meets the predetermined criteria, the device responds to the configuration command by applying one or more configuration settings. Otherwise, if the parameter of the sensed magnetic field does not meet the predetermined criteria, the device ignores the configuration command.
